Caelum is a faint constellation in the southern sky, introduced in the 1750s by Nicolas Louis de Lacaille. Its name means "the chisel" in Latin, and it was formerly known as Caelum Scalptorium ("the engraver's chisel"). It is the eighth-smallest constellation, and subtends a solid angle of around 0.038 steradians, just less than that of Corona Australis. Due to its small size and location away from the plane of the Milky Way, Caelum is a rather barren constellation, with few objects of interest. The constellation's brightest star, Alpha Caeli, is only of magnitude 4.45, and only one other star (Gamma¹ Caeli) is brighter than magnitude 5. Other notable objects in Caelum are RR Caeli, a binary star with one planet approximately 20.13 parsecs (65.7 ly) away; X Caeli, a Delta Scuti variable that forms an optical double with Gamma¹ Caeli; and HE0450-2958, a Seyfert galaxy (pictured) that at first appeared as just a jet with no host galaxy visible. Although it has been suggested that it is an ejected supermassive black hole, the host is now agreed to be a small galaxy that is difficult to see due to light from the jet and a nearby starburst galaxy.
